Abstract
A sensor, method, and system for sensing corrosion. The sensor may be used to monitor the integrity of structural elements. The sensor, method, and system utilizing an inductive element formed on the substrate and having a first inductive loop and a second inductive loop. The sensor also includes a sensing element electrically connecting one end of the first inductive loop to an opposing end of the second inductive loop. Prior to dissolution of the sensing element, an inductance of the inductive element comprises a first inductance set by the first predetermined number of turns of the inductor coil having a first resonant frequency. After dissolution of the sensing element, the inductance of the inductive element comprises a second inductance reduced from the first inductance.
